pypy/dist/pypy/translator/typer.py
Log:
The C typer generates tuples as plain 'struct' variables.
The typer in general seems to converge to a kind-of-elegant solution, even if
the code is a bit verbose at places (e.g. at the end of t_tuple.py). This
should become documentable at some point soon...
Missing: cannot use tuples as return values -- ANSI C compilers don't accept
'struct' types as function return types; and gen_wrapper() in funcdef.py is
becoming messy and needs more messiness to be able to wrap/unwrap tuples :-(
